Dear Christian friends:

Christian churches all over the world rejoice and praise the Holy Triune God today, and we join with them.

In our text Jesus talks to His disciples about the Holy Triune God.

When we hear that God is Triune we should not be bored or uninterested as many are. True, we can't fully understand about the Trinity. That is a mystery. Yet Jesus teaches us that the true God is triune and that God's wonderful love is shown to us in the Trinity. When we hear that God is triune we should be very happy! It shows the God who saves us!


The first person of the Holy Trinity is the Father. The Father loved us sinners and sent His only dear Son to live and die for our sins. People have not always appreciated the father's role in the world's salvation.

In our text Jesus shows this. He says, "All that the Father has is Mine." (verse 15a) Jesus means "all of the Father's love and grace is Mine." Jesus came from heaven to earth to tell the world about the Father's love and mercy for sinners. The world didn't know about the Father's great love for sinners. (Matthew 11:27)

The world knew about father's power and wisdom and His anger against wrong and sinners. Anyone can learn that from nature, and from his reason and conscience. But the world can't know about the Father's love and mercy from nature. Only Jesus, the Son knows that. Jesus’ says, "All things are given to Me from My Father: and no man knows the Son, except the Father; neither knows any man the Father, except the Son, and he to whomsoever the Son will reveal Him." Jesus came to inform the world about the Father's love and mercy for sinners. He summed it up in that Bible verse which is probably the favorite of most Christians John 3:16, "God so loved the world, that He gave His only begotten Son, that whosoever believsth in Him should not perish, but have everlasting life."

So, today we praise and worship the Father, the First Person of the of the Holy Trinity, who loved the world so much! Also today we praise and worship the Son, Jesus, the Second Person of the Trinity, who obeyed the Father's will and fulfilled the Father's love.

Jesus here in our text is giving comfort and support to His disciples on the night before He went to the cross to suffer and die for the world's sin as the Father had planned. This shows the Son's great love for His Father and for the world. He accepts the world's sin and God's anger and curse against sin and sinners. Tomorrow on the cross He will suffer all God's terrible anger against sin and sinners. He will suffer worse than the condemned in hell. He even suffers our shame and death, so that we can have forgiveness of sins and eternal life. The Son's love for sinners is the same as the Father's.

Therefore, today we also praise and honor Jesus, the Son, the Second Person in the Holy Trinity. And last, but not least we praise and worship the Holy Spirit, the Third Person of the Trinity.

The Father and the Son send the Holy Spirit from heaven to guide us and comfort us as we heard last Sunday, Pentecost Sunday. In our text Jesus says to His disciples, "When the Spirit of truth is come, He will guide you into the truth." (verse 13a) As before, Jesus calls Him, the Spirit of Truth." Notice: He is the Spirit of Truth" who leads the disciples “into the truth." Therefore the Holy Spirit teaches the world the truth through the 12 disciples (apostles).

These apostles preached the truth until they died. Although they are dead and have been dead for 1900 years, they still teach us through their writings in the New Testament of the Bible, which the Holy Spirit led them to write. Their holy writings teach us the beautiful truth about the Father's love and mercy for sinners and about the Son who came from heaven to earth to fulfill the Father's plan of salvation, and then returned to heaven.

And from the apostles inspired writings we today witness to all the world, preach the Good News to all nations.

Therefore the Holy Spirit is still leading us Christians and all who hear us into the truth about God's love for sinners.

By radio the men at N.A.S.A. Control Center in Houston, Texas can control or lead the flight of a space ship to the Moon or one of the planets such as Mars, millions of miles away. That is wonderful! But more wonderful it is that God in heaven, by His Holy Spirit can direct and lead the hearts of His people here on earth.

Through the Holy Spirit God leads us to know the beautiful truth about Himself. Therefore, today we also praise and honor the Holy Spirit, the Third Person in the Trinity, our Teacher and Comforter from heaven.

Therefore, let us today join with Christians all over the world to praise and honor and serve the Holy Triune God, Father, Son and Holy Spirit. Many of our fellow Christians will be singing this old favorite with which I end the sermon today:

"Praise God, from Whom all blessing flow,
Praise Him, all creatures here below;
Praise Him above, ye heavenly hosts;
Praise Father, Son and Holy Ghost."
(Praise God From Whom All Blessings Flow, hymn)

Amen.
